Abstract (en)

A process (300) for developing a method of operating a sample separation apparatus (10) for separating a fluidic sample using a mobile phase, wherein the process (300) comprises executing (302) a scouting method (400) for separating a fluidic sample by controlling a set of controlled parameters (C) during the execution of the scouting method (400), wherein non-controlled parameters (Q) are allowed to freely vary during the execution of the scouting method (400), registering (304) a course of at least one non-controlled parameter (Q i ) during the execution of the scouting method (400), defining (308) a modified method (410) for separating a fluidic sample derived from the scouting method (400) by changing (320) the set of controlled parameters (C) and declaring (330) the previously registered non-controlled parameter (Q i ) as a new controlled parameter in the modified method (410), and executing (312) the modified method (410) under application of the registered course of the parameter (Q i ) as execution program for this parameter (Q i ) in the role of new controlled parameter.
